Will a Bible Stop a Bullet!?

Origin:
I was asked the other day if a Bible would stop a bullet? My response was, depends on the Bible. If we are talking the huge family Bible the size of a catholic lectionary, then likely. However, these are really uncommon. You would be more likely to be caught behind one the size of the ones in the pew back. Also, I have a serious issue with desecration of judeo-chriustian religious texts. So we are going to use an "approximate Bible" in the hymnal.That said, when you sit in church, which book is more prevalent in your pew back?

So, full disclaimer, this is not a religious text and is not taking aim at any particular scenario involving conflict inside a church.
